4 Claims.

This invention relates to a box lining and particularly to a lining for a box wherein the side walls are substantially in right angular relation, and it is an object of the invention to provide a 5 lining of this kind which not only serves as a protection for the box content but eliminates the necessity of applying a lid or cover to the filled container.

It is also an object of the invention to provide a lining for a box which when applied ofiers no undue hinderance or obstruction to the desired air circulation within the container and wherein the lining for a single box or container comprises two duplicate sections whereby the application of the lining is materially facilitated without requiring any special skill on the part of the workman.

The invention consists in the details of construction and in the combination and arrange- 20 ment of the several parts of my improved box lining whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter he definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:-

Figure 11 is a view in perspective of a lining 10 section constructed in accordance with an embodiment of the invention as illustrated in Figures 9 and 10 unapplied;

Figure 12 is a view in plan of the blank from which is produced a lining section as illustrated 15 in Figures 9, 10 and 11.

In the embodiment of my invention as particularly illustrated in Figures 1 to 5 inclusive,

B denotes a box or crate of a conventional type wherein the end walls I and the side walls 2 are substantially at right angles and wherein each of the side walls terminates a slight distance above the bottom 3 of the box or crate to provide an opening 4 to facilitate air circulation through the box or crate content for the purpose of 2 ventilation. This box or crate is of a standard design and forms no part of my invention.

My improved lining for the box or crate B as herein disclosed comprises two substantially duplicate sections L each of which is produced from an initially flat blank of paper board or other material possessing the desired weight and quality. As particularly illustrated in Figure 5 of the drawings the blank for the lining section L comprises a panel 5 of dimensions substantially identical with the dimensions of a side wall. 2 of the box or crate B and. against which side wall the panel 5 has close contact from within the box or crate B when the lining section 5 is in applied or working position.

The ends of the panel 5 are continued by the end panels 6 which are separated from the ends of the panel 5 by the score lines I disposed transversely of the panel 5 and upon which the panels 6 readily fold so as to have close contact with the inner faces of the end walls I of the box or crate B when the lining section L is applied.

These panels 6 have end portions 8 extending below the lower marginal portion of the panel 5 for direct contact with the bottom wall 3 of the 7 box or crate B so that the lower marginal portion of the panel 5 will be spaced from the bottom 3 of the box or crate B a distance substantially equal to-the height of the adjacent opening 4 so that the applied lining section will offer no tion of air through the content of the box or crate B for the purpose of ventilation which is particularly desirable when the box or crate B is being employed in the packing and shipping of fruits, vegetables and the like.

'Each of the end panels 6 is of a length substantially equal to one-half of the length of an end wall I of the box or crate B as is particularly illustrated in Figures 1, 2 and 3'so that when the two lining sections are applied the inner faces of the end and side walls of the box'or crate B are effectively covered. The upper marginal portions of the end panels Gare, separated by. the score lines!) from the lockingflaps it. These flaps l areradapted to be folded along the score lines 9 to be disposed inwardly of the box orcrate B above the content of the box or crate B and which content readily holds said flaps in desired working or effective position. The corner portion of each-of the flaps l0 close to the outer edge of the adjacent end'panel 6 is provided with anobliquely disposed slot H extending from a point substantially immediately adjacent to the score line'9 to a point'in'relatively close proximity to the side edge of the flap H3 which is substantially in continuity with the outer edge of the adjacent end panel 6.

The panel has its up er margin defined by a score line. I 2 coplanar with the score lines 9 and which score line [2' separates the panel 5 from a top closing flap 14. This flap [4 is adapted to swing inwardly of th'e box or crate above .thepreviously positioned flaps ID. The outer free corner portions [5 of this flap I4 are readily insertable through the slots H whereby the flap I4 is held in'closed position as illustrated in FigureslZ; 3 and 4.

.As' is clearly disclosed in the accompanying drawings, theiend portion 'of each of the flaps I4 is of a length less than. the intermediate or major portion of the flap. This is done'so that 'when' the lining section has been applied the desired interlocking of the outer corner portions ofthe flap M with the end panels; I0 'is materially facilitated.

With my improved lining applied it is 'to' be noted; asillustrated in Figures 2 and 3, that the normally open top of the box or crate B is effectively closed and in a manner to assure desired protection of the content and, therefore, with the use of my improved lining it isnot necessary that the con'ventionalllid 'or cover be applied to the box or crate although ofcourse this can be done if desired. It is also'to be stated that my improved lining is particularly adaptable for use in connection with packages wherein the content of the. box or crate'does not materially extend walls of the box. or crate.

. In the embodimentof the invention as illustrated in Figures 6, 7 and 8,'the lining section L is of substantially the same constructionas' each of the lining sections L hereinbefore referred to except that the lower edges of the end panels 6 are substantially flush with the lower edge of the side panel 5' or, in other words, the end panels 6 as well as the panel 5' are of a height substantially equal to the height of the adjacent side wall ofthe box or'crate in which thelining section L" is applied.

The upper inner corner portion of each of the -end panels 6" has cut therefrom a tab I6 which, when the end panels 6' are swung inwardly on the score lines I, remain substantially coplanar the side with the panel 5 sothat said tab IE will extend beyond the opposite ends of the panel 5' to contact from above with the upper marginal portion of a side wall 2' of the box or crate B' or to slip between the upper marginal portion of a sidewall 2' and the upper portion of the adjacent vertical edge of an end wall I as is'illustrated in Figures 6 and '7 of the drawings. These tabs l6 serve to provide support for an applied lining section L with the lower margin of the panel 5 of such section spaced above the bottom 3 of the box or crate B so that'no hinderance or obstruction will be offered to the'opening 4' to allow for the desired ventilation ofthe content of the box or crate 'B'.

In Figures 9, 10, 11 and 12 I disclose an embodiment of my invention which can'be employed with equal facility within a conventional box or crate or in connection with a box or crate comprising in its structure the corner bracing posts P. The lining as comprised in this form of my invention also embodies two substantially duplicate sections LZeach of which is produced from an initially flat blank of paper board or other material possessing the desired weight and quality; Each of these sections L has a panel 5" tr dimensions substantially identical with the dimensions of a side wall 2" of the box or crate 'B" and againstwhich side wall the panel 5" has close contact from within.

The ends of the panel 5" are continued by the end panels 6" which are separated from the ends of the panel 5" by the score lines 'I" and upon which the panels 6 readily foldgin order to have desired close contact with the inner faces of the end walls I of the box or crate B". The panels 6" have portions 81 extending below the lower marginal portion of thepanel 5" for direct contact with the bottom wall 3 of the box or, crate B" so that the lower marginal portion of the panel 5" will be spaced from the bottom wall 3" 'of the box or crate B" a distance substantially equal to the height of the ad acent opening 4" atthe lower portion ofthe side of thebox'so that the applied lining section L will offer no hindrance or obstruction to air circulation through the box or crate content.

The distance between the score lines 1 is substantially equal to the distance between the :ly thereof contacts with a corner post P.

From the foregoing description it is thought to be obvious that a box lining constructedin accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and'emvention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the pre-' ployed, and it will also be obvious that my in- I claim:-
